Problems solved by technology

However, due to the molecular structure and other reasons, the surface scratch resistance of polypropylene materials is poor, which greatly reduces the aesthetics of the product. The scratches on the surface of the product often lead to stress concentration and reduce the mechanical properties of the material. limited its field of use
At the same time, due to the physical and chemical properties of the currently commonly used scratch-resistant agents, the volatile organic compound (VOC) content of the material is too high, which cannot meet the strict requirements of automotive interior parts on odor, atomization, etc.

Abstract

The invention discloses a low-volatile nano filler modified polypropylene material, a preparation method and application thereof. The low-volatile nano-filler modified polypropylene material contains the following components in mass percentage: 60-75% of polypropylene, 19.3-30% of nano-silicon carbide whisker masterbatch, 5-15% of ethylene-octene copolymer, 0.1-0.4% of antistatic agent, 0.1-0.6% of antioxidant and 0.1-0.5% of ethylene-acrylic acid copolymer wax. The present invention uses random copolymerized polypropylene as the resin base material, and improves the scratch resistance of the polypropylene material by adding self-made nano-silicon carbide whisker masterbatch, antistatic agent and ethylene-octene copolymer for modification. Reduced performance. The modified polypropylene prepared by the invention can be widely used in the fields of automobiles and home appliances.

Description

Technical field [0001] In the field of modification techniques of a polymer composite, the present invention relates to a low volatile nanfillerative modified polypropylene material and a preparation method thereof. Background technique [0002] As people have increasing the living environment, automotive manufacturers also put forward new, higher requirements for the control of the volatile low molecular compound of automotive interior materials, good touch and scratch resistance of materials. . However, due to molecular structures, the surface of the polypropylene material is poorly scratched, and the aesthetic level of the product is largely reduced, and the scratches produced on the surface of the article are often concentrated, and the mechanical properties of the material are reduced. It limits the field of use. At the same time, since the physicochemical properties of the currently used scratch resistant itself causes the material to volatile organic substance (VOC) conten...
